A student is solving the equation 81x – 1 = 3x + 2.
Step 1: 81x – 1 = 3x + 2
Step 2: (34)x – 1 = 3x + 2
Step 3: 34x – 4 = 3x + 2
Which is the next step?
Possible answers
4x 4 = (x + 2)

x 1 = x + 2

4x 4 = x + 2

4(x 1) = 3(x + 2)

    How do you get from step 1 to step 2? Do you have some typos?

    Subtract 3x and add 1 to both sides of the equation.
